HAN D-STAM P.

SPECIFICATION forming part of Letters Patent No. 462,066, dated October27, 1891. Application filed January 7, 1891. Serial No. 376,989. (Nl)model.)

To all whom it may concern.

Be it known that l, WILLARD W. SAWYEE, a citizen of the United States,residing at Springfielchin the county of Hampden and State ofMassachusetts, have invented certain new and useful Improvements inHand- Stamps, of which the following is a specification, referencebeinghad therein to the accompanying drawings.

This improvement relates to that class of hand-stamps shown in myapplication, Serial No. 372,459, filed November 24, 1890, in which thereare a series of numbering-wheels,whioh are so arranged that the samenumber may be repeated as frequently as desired, or the position of thewheels may be changed so as to Vary the number to be printed; and theinvention consists in the peculiar construction, arrangement, andcombinations of parts hereinafter more particularly described and thendefinitely claimed.

In the accompanying drawings, Figure 1 shows a front view of a stampconstructed according to my improvement; Fig. 2, a back View of thesame. Figs. 3 andiare side views of the stamp with one of the sides ofthe frame broken away and the parts in different positions.

Referring now to the details of the drawings, 1 represents the frame, inwhich slides the plunger 2, to which is attached the fork 3, carryingthe numbering-wheels at, each being provided with a ratchetwheel on itsside and mounted on a shaft 5, projecting through the sides of the forkand working in grooves 18 in the frame, all as shown in my previousapplication above referred to, and, like the plunger in said stamp, theplunger in this stamp is hollow and is provided with a spiral spring 6to lift the plunger, fork, wheels, &c., after the stamp has been used.All of these parts so far described are substantially the same as thecorresponding parts in my previous application above referred to, and afurther description of the same is not therefore necessary.

Mounted in the shaft 5 is a yoke 7, in which is pivoted a pawl-carrier8,which operates on the ratchet-wheels of the numbering-wheels 4 in amanner well understood, and is fully shown and described in my aforesaidapplication. On the ends of the arms of the yoke are formed .coggedsegments 9, which mesh with corresponding teeth 10, formed on the lowerends of the bifurcated lever 11, pivoted by the screws 12 to the top ofthe fork Between the fork 3 and the n umbering-wheels is secured aspring 13, the free end of which presses against the lever 11 and tendsto keep the same in the position shown in Fig. 3. A cam-surface isformed on the lever 11 at 14c, whose object will be hereinafterexplained.

Mounted upon the shaft 5 is another yoke 15, pivotally connected by ascrew 20 with the inking-pad 10, which latter is pivoted to the sides ofthe frame by a screw 17 passing through the frame 1, as shown in dottedlines in Fig. 2.

The operation is as follows: Supposing that a series of papers are to bestamped with the same number-as, for instance, in the papers connectedwith the registration of a letter the stamp is placed upon one of thearticles to be stamped and the handle depressed, which carries down thewheels, (the yoke 15 pushing the inking-pad 16 out of the way,) and theimpression is made upon the paper or other material to be stamped. Assoon as the pressure on the handle is removed the spring 6 causes theplunger-wheels, &c., to rise, and the yoke 15, acting on the inkingpad,will bring the same again in contact with the type-wheels, as shown inFig. 3. If two or more papers are to be stamped with the same number,the operation is repeated as many times as necessary until all thepapers that are to be numbered with the same number have been stamped.If it is now desired to stamp another set of papers with the nextconsecutive number, the finger of the operator is pressed on the upperend of the lever 11', which causes the cam let to act upon the underside of the frame,and thus slightly depresses the plunger, which, actingon the yoke 15, will move the inking-pad 16 slightly away from thenumbering-wheels, and as the pressure on the lever is increased theteeth on its lower end,acting on the segments 9 on the yoke 7, givemotion to said yoke and with it the pawl-carrier 8, whose pawls operateon the ratchet-wheels on the side of the numbering-wheels, and thus,assuming the posi- ICO tion in Fig. 4, bring the next consecutive 11umberin position. The stamp is then placed on one of the papers to bestamped with said number, and all the papers requiring the number thenin the printing position are now stamped. As the stamp rises after thefirst impression has been taken the spring 13 acts upon the lever andthe yoke and pawl-carrier assume the normal position, as shown in Fig.3, Where it is ready to be used to move the numbering-wheels, as before,when the next number is required to be printed. By this construction annmbering-machine may be made that will be found to be cheaply made,Very convenient in operation, and not liable to get out of order. Insome cases I may dispens'e with the teeth and segments and connect thelever and yoke by a link, as shown in dotted lines in Fig. 4. It isobvious that as the lever 11 is operated said link, being pivotallyconnected with both the lever and yoke, will transmit motion from thelever to the yoke, and thus the latter will swing on itscenter insubstantially the same way as if the yoke and lever were connected bythe segments 9 and 10.

Having thus shown what 1 consider the preferable way of carrying outmyinvention, but without limiting myself to the exact construotiondescribed or illustrated,what I claim as new is 1. Thecombination,inanumbering-stamp, of a frame, a fork, ahandle connectedthereto for depressing said fork in said frame, a set of numbering-wheels mounted therein, a yoke and pawl-carrier operating saidwheels, a lever pivoted on said fork having its operating end arrangedin proximity to the handle, and intermediate connections between theoperating end of the lever and the yoke, substan tially as described.

2. The combination, in a numbering-stamp, of a set of nu mbering-wheels,the yoke 7, having segments 9, a pawl-carrier mounted in said yoke, andthe pivoted lever 11, having teeth 10 engaging with the segments 0,substantially as described.

The combination, in a numbering stamp, of a fork, a series ofnumbering-Wheels mounted therein, inking mechanism therefor, and a leverpivoted to the fork, having a cam acting against the undersurface of theframe, substantially as described.

4-. The combination, in a numbering-stamp, of a set of numbering-wheels,inking mechanism therefor, a yoke 7, having segments 9, aPttWl-Cttll'lGl mounted in said yoke, and the pivoted lever 11, havingteeth 10 and cam surface l l, substantially as described.

5. The combination, in a n nmbering-machine,of a set of numbering-Wheels mounted in a fork 3, a yoke 7, having segments 9, apawlcarrier mounted in said yoke, apivoted lever 11, having teeth 10 andcam-surface 11, a yoke 15, connected to the fork 3, and a swinginginking-pad l0, pivoted to the said yoke, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses,this (5th day of January, 1891.
